After months of hard work Clarkson's farm arrives at a make or break moment; harvest time. 'It's always stunning on the farm, actually. Whatever the day, there's always something that's absolutely beautiful. The thing is, the show's now over, which is sad. But thank you very much for being so patient with me.'

This featured film investigates the emerging threats posed by plastic pollution to life on Earth. The hyper-convenience of our modern way of living produces staggering volumes of plastic waste daily. Scientists now know that this waste breaks down into ever tinier pieces, spreading right across the globe and posing direct health risks, including through bioamplification of toxic additives moving up the food chain. We explore the drastic changes it will take to deliver a sustainable future for our planet.

NASA's brand-new Mars rover is on the hunt for alien life, and with the help of cutting-edge engineering, scientists embark on a search for fossilized remains, which might prove the Red Planet was once home to a vast ocean and extraterrestrial life. Perseverance carries seven scientific instruments to study the Martian surface at Jezero crater. It carries several cameras and two microphones. The rover is accompanied by the helicopter Ingenuity, which will help Perseverance to scout for locations to study.

Across the world, rising demands for food, water and materials have pushed resources to the limit. Many parts of the world have major challenges over fresh water. A lot of soils have a lot of residual pesticides and herbicides. At the same time waste is piling higher. All this demands a new wave of innovation. The challenge is to make more of the things we need without the environmental cost.

With a million species at risk of extinction, Sir David Attenborough explores how this crisis of biodiversity has consequences for us all, threatening food and water security, undermining our ability to control our climate and even putting us at greater risk of pandemic diseases.
Everything in the natural world is connected in networks that support the whole of life on earth, and we are losing many of the benefits that nature provides to us. The loss of insects is threatening the pollination of crops, while the loss of biodiversity in the soil also threatens plants growth.
Last year, a UN report identified the key drivers of biodiversity loss, including overfishing, climate change and pollution. But the single biggest driver of biodiversity loss is the destruction of natural habitats. Seventy-five per cent of Earth's land surface (where not covered by ice) has been changed by humans, much of it for agriculture, and as consumers we may unwittingly be contributing towards the loss of species through what we buy in the supermarket. Human activities like the trade in animals and the destruction of habitats drive the emergence of diseases. Disease ecologists believe that if we continue on this pathway, this year’s pandemic will not be a one-off event.

Cooking shows turned the humble garlic bulb into something that's essential to cuisines and into a multi-billion-dollar crop. Every year, humans consume nearly 50 billion pounds of garlic, and most of it comes from one country: China. But a lawsuit raises troubling questions about suppliers.
